Abstract
Disclosed are various embodiments for prematurely terminating a flush cycle. A valve stem may be coupled to a cable to move the valve stem in an upward direction to initiate a flush cycle. A buoyant float may be configured to engage the valve stem to prevent the valve stem from moving in a downward direction during the flush cycle, until a water level drops below a predefined level. Finally, a second cable coupled to a valve release assembly may be utilized to release the valve stem from the buoyant float to prematurely terminate the flush cycle.
